All the atoms in a zinc blende structure are 4-coordinate. The zinc blende unit cell is shown in . A number of inter-atomic distances may be calculated for any material with a zinc blende unit cell using the lattice parameter (a).

Sphalerite can have Spinel Law twins, where the twin axis is [111]. 1996-02-01 The F parameter for zinc-blende InN should be -2.77. In Table XI, the Gamma-valley and X-valley gaps for zinc-blende AlN are interchanged (although they are correct in the text), and the correct value for the F parameter in AlN is -0.76 (rather than 0.76 in the text). Zinc blende material parameters. For materials which are not known to the database and for the use of nondefault values for some of the parameters of a known material. For totally unknown materials, all parameters must be specified in the input file.

I looked up the value and I've found it to be a = [itex]\frac{4}{\sqrt{3}}[/itex]l The way that I started my derivation was saying that each tetrahedron has a sulfide ion in the center, so then we can make a triangle from the center point, and two zinc adjacent atoms.

Related content Structural and magnetic properties of CrSb compounds: NiAs structure S Polesya, G Kuhn, S Mankovsky et al.- The lattice parameter has a stronger influence on the minimum energy losses in channeling of zinc-blende compounds than the A or Z of the host-lattice atoms. The Z dependence of incident light ions channeled in a given host lattice is the same as that for normal energy losses.

Here, the bowing parameter is not constant, it depends on the alloy composition x. Thus, this bowing parameter is given by: C ABC (x) = -0.127 + 1.310 * x (Table XII., I. Vurgaftman et al., J. Appl. Phys. 89, 5815 (2001)) In order to describe such a material, we introduced a new type of material: ternary2_zb
